A new issue of Accounting, Economics and Law has published a series of articles (open access) on Minsky and banking. In addition to my contribution, you can find some nice pieces by Thorvald Moe, Yuri Bondi, and Robert Boyer.
According to Minsky, “A capitalist economy can be described by a set of interrelated balance sheets and income statements”. The assets on a balance sheet are either financial or real, held to yield income or to be sold or pledged. The liabilities represent a prior commitment to make payments on demand, on a specified date, or when some contingency occurs. Assets and liabilities are denominated in the money of account, and the excess of the value of assets over the value of liabilities is counted as nominal net worth. All economic units – households, firms, financial institutions, governments – take positions in assets by issuing liabilities, with margins of safety maintained for protection. One margin of safety is the excess of income expected to be generated by ownership of assets over the payment commitments entailed in the liabilities. Another is net worth – for a given expected income stream, the greater the value of assets relative to liabilities, the greater the margin of safety. And still another is the liquidity of the position: if assets can be sold quickly or pledged as collateral in a loan, the margin of safety is bigger. Of course, in the aggregate all financial assets and liabilities net to zero, with only real assets representing aggregate net worth. These three types of margins of safety are individually important, and are complements not substitutes.
If the time duration of assets exceeds that of liabilities for any unit, then positions must be continually refinanced. This requires “the normal functioning of various markets, including dependable fall-back markets in case the usual refinancing channels break down or become ‘too’ expensive”. If disruption occurs, economic units that require continual access to refinancing will try to “make position” by “selling out position” – selling assets to meet cash commitments. Since financial assets and liabilities net to zero, the dynamic of a generalized sell-off is to drive asset prices towards zero, what Irving Fisher called a debt deflation process. (To some extent, this can be called a liquidity problem – but it is really more than that. I’ll return to this later.) Specialist financial institutions can try to protect markets by standing ready to purchase or lend against assets, preventing prices from falling. However, they will be overwhelmed by a contagion, thus, will close up shop and refuse to provide finance. For this reason, central bank interventions are required to protect at least some financial institutions by temporarily providing finance through lender of last resort facilities. As the creator of the high-powered money, only the government – central bank plus treasury – can purchase or lend against assets without limit, providing an infinitely elastic supply of high-powered money.
These are general statements applicable to all kinds of economic units. continue reading…
